What is a conspiracy?
A simple article from the CNN.com to practise your English and know more about the President J. F. Kennedy’s death.

During the half century since President John F. Kennedy was assassinated, you may have heard about a few conspiracy theories.

Decades of investigations, hearings, documents, records, books and interviews have failed to satisfy conspiracy theorists with a definitive answer to The Question: Did Lee Harvey Oswald act alone when he shot the President?

At one time or another, doubters of the lone gunman theory “have accused 42 groups, 82 assassins and 214 people of being involved in the assassination,” said author Vincent Bugliosi.

That’s a lot of paranoia.

So, when reporters, producers, or amateur historiansare looking to check out the latest JFK conspiracy theory, they call Dave Perry. “People think I’m an anti-conspiracy guy,” Perry said recently at his Dallas-area home.

But there’s one theory that he’s not ruling out. We’ll get to that in a minute.

Kennedy assassination conspiracy theorists, Perry said, come in all degrees of interest and levels of obsession. They may believe that the government was behind the 9/11 attacks or that the moon landings were fake. Those folks comprise the “off the wall” crowd. The others, he says, read the books, watch the documentaries and come to less extreme conclusions.
